ee.Geometry.Polygon.edgesAreGeodesics
Returns true if the geometry edges, if any, are geodesics along a spherical model of the earth; if false, any edges are straight lines in the projection.
| Usage | Returns |

Examples
// Define a Polygon object.
var polygon = ee.Geometry.Polygon(
[[[-122.092, 37.424],
[-122.086, 37.418],
[-122.079, 37.425],
[-122.085, 37.423]]]);
// Apply the edgesAreGeodesics method to the Polygon object.
var polygonEdgesAreGeodesics = polygon.edgesAreGeodesics();
// Print the result to the console.
print('polygon.edgesAreGeodesics(...) =', polygonEdgesAreGeodesics);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(polygon,
{'color': 'black'},
'Geometry [black]: polygon');
